Bug #17297012 MEMORY LEAK IN MYSQL_OPTIONS WHILE CALLING WITH OPTION MYSQL_SET_CLIENT_IP

Igor Solodovnikov · Igor Solodovnikov · commit 938e37027e02 · 2013-08-30T21:56:43.000+03:00
Memory Leak in mysql_options() was caused by missing call
to my_free() in MYSQL_SET_CLIENT_IP branch. Fixed by adding
my_free() to cleanup mysql-&gt;options.client_ip value before
assigning new value.
